UNITED STATES PATENT OFFICE.

W. F. MESSENGER AND HENRY REHAHN, OF NEW YORK, N. Y.

COOLER.

Specification of Letters Patent No. 18,263, dated September 22, 1857.

To all whom it may concern:

Be it known that we, W. F. MnssENoER and HENRY REHAI-IN, both of the city, county, and State of New York, have invented a new and Improved Cooler Designed to be Applied to Casks or Vessels Containing Liquids on Draft; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure l is a longitudinal vertical and central section of our improvement applied to a cask, the cask not being bisected. Fig. 2 is a transverse vertical and central section of the same, also applied to a cask, the cask also being bisected.

Similar letters of reference denote the same parts in both figures.

Our invention consists of a hollow vessel for receiving the ice, made in the form of a saddle, so that it may be readily set or placed on the top of barrels or casks containing the liquid to be refrigerated.

The invention is more especially designed to be applied to small or medium-sized casks or vessels which contain liquids on draft, such as are drawn from the tap, and the vessels consequently exposed to the heat as they are generally placed in accessible places above ground, instead of being in cool sub-cellars.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A, represents a curved chamber or saddle which is made to correspond in form to that of the upper part of the cask or vessel B to which it is applied. This chamber is equal in length to the cask B, and extends about half way or rather more around its periphery, as shown in Fig. 2. The chamber A may be constructed of sheet metal. Zinc would probably do as well as any other material.

Through the center of the bottom of the chamber A, an opening (a) is made to allow the plug (a of the cask to project through, and at the bottom ends of the chamber A, at each side, a grating (79) is placed, and a plug (0) is fitted in each bottom end of the chamber.

G, is a chamber which is formed over the chamber A, and covers its outer surface. This chamber is not as deep as the chamber A; it is scarcely half its depth. Through the center of the chamber C, a square opening is made and a rectangular box D is fitted therein. This box D serves as a cover to the chamber A, around the opening (a) in the bottom of the chamber A.

The chamber A is filled with ice (6), and chamber C is filled with plaster-of-Paris (f), or other non-conducting material. The waste water is allowed to escape from chamber A by withdrawing the plugs It is well known that, when liquids are placed in any vessel, there is a tendency in the warmer particles to rise to the upper part or surface while the colder particles sink to the bottom. Then our refrigerating saddle is applied to the top of any cask or barrel, the warmer particles of the liquid therein contained are quickly cooled, and after the contents of the cask have become cool, the saddle will serve, to a certain extent, to continue the refrigeration even after the ice contained in the saddle has been melted.

One great advantage of our refrigerating saddle is that it may be changed from barrel to barrel at pleasure.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is:

The refrigerating saddle A, made substantially as herein set forth.
